Our study in the Journal of the Royal Society of Medicine (here, here, and here) shows that the majority of the Victorian urban poor consumed diets which were limited, but contained extremely high nutrient density. Bread could be expensive but onions, watercress, cabbage, and fruit like apples and cherries were all cheap and did not need to be carefully budgeted for.
Show me a grocery store where fresh watercress and cherries are cheaper than some artificial crap loaded with added sugar, sodium, and preservatives, and people will start to eat healthier.
